This paper presents new refined results from the theoretical treatment of electron collision with the Fe-peak element Co3+. We have investigated the relevance of relativistic effects on the accurate representation of the target electron wave functions within theBreit-Pauli R-matrix approach. The calculated values for fine-structure levels are compared with the available experimental data in Atomic Structure Database of the National Institute for Standards and Technology. The agreement between

For completeness, we summarize herein the existing theoreticalR-matrix treatments intended specifically to explore the role of including configuration interaction wave functions both in the target-state expansion, and in the ()-electron quadratically integrable function expansion. To the best of our knowledge, the work reported herein describes for the first time a detailed calculation for this atomic system, and the results are relevant to the laboratory and astrophysical plasmas.
